FIREPLACE DAMPER,

To all whom it may concern:

Be it known that'I, JOHN M. Goonwm, a citizen of the United.States,.residing at San FI'EIHCISCO IIIthG county of San Francisco andState of California, have invented new and useful Improvements inFireplace Dampers, of which the following is a specification. v Y

This inventionrelates to improvements in fire placefdampers and has.particular ref: erence to an apparatus for the control of drafts-in openfire places.

One object of this invention is to provide a' damper for an open fireplace which may be operated from thefront outside of the chimney hearthto adjust the-apparatus to various positions and retain the same in suchpositions when adjusted. .Another object of'this invention is to providea damperof the character described which is simple in construction,economical in-manufacture, and in whichthe parts are so designed and.arranged that they can .be readily. put into operative condition andplaced in the fire place by unskilled labor.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawlng'forming a part of this application'and'which like numerals are employed toldesignate like .parts throughout'thesame,

. Figure 1 is a frontelevation-of an'open fire placeshowing. theapparatus iniposition,

Figure 2 is a vertical sectional view taken on the line22 of Figure 3,

, Figure 3 is a horizontal sectional view taken on the line 3-3 ofFigure 1, and

Figure 4 is a View in detail showing a fastening forming part of myinvention.

In the drawing wherein for the purpose of illustration is shown'apreferred embodi ment of my invention, the numeral 5 represents a fireplace of any approved construction, which is provided'with a casing 6,to which casing is attached a fastening 'element 7'. In the passage way8 of the chim ney 9 there are placed a pair of supporting strips 10, thestrips being positioned par.- allel with the side walls of the chimney.Each support terminates in an up er bent end 11 and a bent end portion12. y referring to Figure 2 it will be observed that the bent ends 11are embedded in the walls of the'chimney, while the bent end portions 12engage a rectangular frame 13.v

' .The construction of the frame .13 and its.

positionwithin the throat of the chimney is it will be noted that apair-of connecting rods 14 are journaled inthe frame. Suit;

Thisweight element is-positioned to lie directlybeneaththe con; tactingpoint of thearched plates 15, andby force of gravity willoalwaysb edisposed in 1 this position.

To illustrate this feature I have shown I means of access, shown as awhole by the ,skilled in the art it willbeiapparent that I numeral 23,which means can be built inthe chimney.

whole apparatus can be lowered into that type of chimney where thisoperation is deemed advisable.

Attention is called to the fact that the parts of this apparatus can bereplaced if they are burned out or are injured and need replacement. Inmaking the various parts a cheap class of material easily worked intoshape and at the same time of a durable design, can be readily employed..When the apparatus is placed within the chimney there is nothingvisible except the fastening element 7 and the ends of the cable, whichelements can be made of an ornamental character and thus add to theattractiveness of the attachment.

It is to be understood that the form of my invention herewith shown anddescribed, is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of th invention or thescope of the subjoined claims.

Havingthus described my invention, I claim p 1. In combination with achimney, a damper comprising a frame, supporting strips having one endof each strip secured in the wallof said chimney and the opposite end ofeach strip engaging said frame,plates pivotally connected with saidframe, a weight element connected with and suspended from the lowerextremities of said plates, and means connected with and adapted tocause said plates to be moved into and out of engagementwith each other.

2. In combination with a chimney, a damper "comprising a rectangularframe, supporting strips having one end of each strip secured in thewall of said chimney and the opposite end embracing said frame, archedplates mounted within said frame and pivoted thereto, a weight elementsus pended from said plates, a cable connected with and adapted tocontrol the movement of said'plates and extending downward through thechimney to the front of the fire place, and means for receiving saidcable to hold it in an adjusted position.

3. In combination with a chimney, a damper comprising a rectangularframe, supporting strips, each ofsaid strips terminating in a flangedportion at one end thereof and adapted to be fastened in the wall ofsaid chimney and terminating at the opposite end thereof in a bentportion and adapted to embrace said frame, arched contacting platesmounted within and pivoted to said frame, a cable connecting said platesadjacent the lower extremities thereof'and suspended therefrom, a weightelementsecured to said chain and positioned beneath the contacting.point of said plates, and means connected with said plates adjacent theupper extremities thereof and extending downward and outward through thechimney for controlling the movement of said platesf 4.
